CHARGING DEVICE FOE SHAFT FURNACES.

Application filed March 8, 1.924.

T all whom it may concern:

Be it known that I, HUG-O LUYKEN, a German citizen, and residing atBielefeld, Germany, have invented certain new and useful 5 Improvementsin Charging Devices for Shaft- Furnaces, of which the following is aspecification.

hen charging shaft-furnaces over an inclined chute terminating in theshaft of the latter, usually, the drawback occurs that the coarseportion of the charge separates from the fine portion of the same, sothat the dis tribution of the charge in the shaft of the furnace becomesnon-uniform and results in an irregular burning and draught therein andthus in a reduced capacity of the furnace.

The present invention provides improved means by which this drawback iseffectively overcome.

The accompanying drawing represents the improved arrangement in asectional side elevation.

The furnace a has at the top end of its shaft Z) an inclined chargingchute c in a way known in the art.

According to the present invention, said chute 0 extends somewhat intothe shaft by means of a removable piece d, while the latter is protectedagainst the ascending heat and flame in the shaft by means of a guard ewhich extends from said piece in rectangular downward direction andwhich preferably terminates in the furnace shaft wall. Underneath saidchute extension piece d and on the opposite side of the inner furnacewall, a downwardly inclined baffle- Serial No. 697,927.

plate f is provided on the latter, which, like the chute extension pieced, has a guard g extending therefrom in rectanguiar downward directionand preferably terminating in the furnace shaft wall.

By these means, the fuel distribution in the furnace shaft becomesalmost perfect and the capacity of the furnace is thereby considerablyincreasedacc'ording to experiments actually made, up to and more.

. What I claim,v is:

1. In combination, a shaft of a shaftfurnace, an inclined charging chuteat the top end of said shaft, a removable extension piece on said chuteprojecting somewhat into said shaft, and a downwardly inclinedbaffle-plate located underneath said chute extension piece and on theopposite side of said shaft, substantially as and for the purpose setforth. I

2. In an arrangement as specified in claim 1, a guard against heat andflame provided both on said chute extension piece and on saidbaffle-plate and extending therefrom in rectangular downward directionand terminating in the wall of said shaft, substantially as and for thepurpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
